This is a spiral format of four months of time, with two colours (nice choices too) indicating sleep/awake patterns of a newborn baby. omg the first month is hard. I’m only 5½ months into being a dad, and I’ve already forgotten about it.
On twitter you’ll see some people objecting to the spiral format, and it’s true that there is distortion with the early days taking up less space on the screen, but you trade that for eye-catching (GU6) and the continuity of time. No perfect mapping into visual parameters.
